When to use it
Use it when you need a few minutes of someone's time and know they're busy. Asking for their take is respectful, and saying how long it will take lets them say yes or suggest a better time. You don't need to apologize for a normal work request.
Example
You: “Could I get your take on something? It'll take five minutes.”
Senior colleague: “Sure, I have time after this call.”
In an email or Slack message
In Slack or email, skip the apology and include the question: “Could I get your take on the pricing slide? It's a 5-minute read: [link]. Any time today works.” People answer faster when they know the ask.
